Abstract

The utility model relates to a overcooled parallel-flow type condenser, comprising a condenser and a reservoir. The condenser comprises a collecting pipe 1 and a plurality of porous flat tubes 4 with heat sink, which is characterized in that the condenser is divided into condensing and overcooling parts. The reservoir is a slender tube shape and is brazed together with the collecting pipe 1 of the condenser. The utility model has the advantages of simple structure, convenient arrangement and maintenance, good refrigeration, lower production cost and that can be suitable for the air-conditioning system of automobile.

Description

A kind of cold mould parallel flow condenser of crossing

The utility model relates to a kind of parallel flow condenser, especially a kind of mistake cold mould parallel flow condenser of used for automobile air conditioning.

Present most automotive air-conditioning system, from the HTHP gaseous coolant of compressor output by condenser heat radiation becoming high-temperature liquid state refrigerant, and then input reservoir, condenser and reservoir are two independently parts, link together by connector.The function of reservoir mainly is when the air-conditioning system operating condition changes, the refrigerant of absorption and replenishment cycles refrigeration and the additional refrigerant that leaks from system's attaching parts.The refrigerant that injects from reservoir top makes reservoir refrigerant liquid level be in turbulent condition.For preventing that turbulent flow from causing gaseous coolant to be involved in, add the refrigerant about 150 grams; Mostly the refrigerant of condenser input reservoir is the gas-liquid two-phase coexisting state in addition, wherein have approximately about 10% to the adiaphorous gaseous coolant that freezes, supply with evaporimeter through the throttling of expansion valve.In order to reduce the gaseous state generating capacity of evaporator inlet portion, it is cold excessively through a condenser again before refrigerant enters expansion valve, thereby, this cold excessively air-conditioning system reached the purpose that improves refrigerating capacity though having reached the gaseous state generating capacity that reduces evaporator inlet portion, but also to inject more refrigerant, and system unit and connecting tube increase, not only increase installation difficulty and cost, and increased little leakage chance.

The purpose of this utility model is the problem at above-mentioned existence, and a kind of cold mould parallel flow condenser of crossing is provided, its compact conformation, simple, install and keep in repair more convenient, good refrigeration effect.

The utility model is achieved in that it is made up of condenser and reservoir two most institutes, and parallel flow condenser is made up of header, some porous flat pipes and fin.The header two ends are by being provided with end cap seal, and its inside is provided with some partitions header is divided into plurality of sections, the effect of playing shunting in the course of the work and confluxing.Use porous flat pipe between two headers, claim harmonica-shaped tube to connect again, between the corresponding partition section of each between two headers, be communicated with folder weldering fin between the porous flat pipe, fin band shutter by some parallel porous flat pipes.

Architectural feature of the present utility model be with thick reservoir structure originally change into elongate structure and with a header soldering of condenser be one, utilize the import of reservoir and the optimal design of exit position, condenser is divided into condensation and crosses cold two parts, partly cool off the back from the HTHP gaseous coolant of compressor output by condensation and enter reservoir near the position of refrigerant liquid level from reservoir, filter through reservoir, dry refrigerant again from outlet enter condenser to cross cold spots cold excessively, this device can not produce turbulent flow and cancel connecting tube because of refrigerant input reservoir, the gas-liquid mixed refrigerant of reservoir output passed through the cold spots cooling again, the gaseous coolant generating capacity at evaporator inlet place is reduced, if by refrigerating capacity and former identical setting of air-conditioning system, can reduce compressor displacement to reach and save 10% power, save about refrigerant 100 grams.

The utility model is simple and reasonable, and fully energy savings reduces refrigerant consumption, improves the air conditioning for automobiles installation capability simultaneously.

Below in conjunction with drawings and Examples the structure of the present utility model and the course of work are further described.

Fig. 1 is the utility model structural representation, and accompanying drawing also makes an abstract.

Among the figure, the 1st, header, the 2nd, partition, the 3rd, end cap, the 4th, band fin porous flat pipe, the 5th, reservoir.

Referring to Fig. 1, the utility model is condenser and 5 liang of most compositions of reservoir, and wherein condenser is made up of header 1, some the flange-cooled porous flat pipes 4 that be arranged in parallel.Header 1 two ends are by being provided with end cap 3 sealings, and its inside is provided with some partitions 2 header 1 is separated into plurality of sections, the effect of playing shunting in the course of the work and confluxing.With some porous flat pipes 4, claim harmonica-shaped tube to connect again between two headers 1, be communicated with by some parallel porous flat pipes 4 between each corresponding partition section that two headers are 1.Architectural feature of the present utility model be with thick reservoir 5 structures originally change into elongate structure and with a header soldering of condenser be one, utilize the import of reservoir 5 and the optimal design of exit position, condenser is divided into condensation and crosses cold two parts, partly cool off the back from the HTHP gaseous coolant of compressor output by condensation and enter reservoir 5 near the facial position of cooling medium liquid from reservoir, filter through reservoir, it is cold excessively that dry refrigerant exports the mistake cold spots that enters condenser from reservoir 5 again, this device can not produce turbulent flow and cancel connecting tube when importing reservoir 5 because of refrigerant, the gas-liquid mixed refrigerant of reservoir 5 outputs passed through the cold spots cooling again, the gaseous coolant generating capacity at evaporator inlet place is reduced, reach the purpose of saving power and refrigerant.

The utility model is simple in structure, install and keep in repair more convenient, good refrigeration effect, production cost is low, the air-conditioning system that is fit to automobile is used.
